GREEN RIVER COMMUNITY COLLEGE HS REPLACEMENT: GENERAL
CLASSROOM BUILDING
SEPA NO. N/A

GRA NO. GRA08 -0041
BUILDING PERMIT NO. BLDO8 -0243
Site Address:
The project is located in NW '/4, Section 16, Township 21 North, Range 5
East, W.M., 12401 SE 320th Street, Auburn, WA 98092. The tax parcel
number is 162105 - 9006 -07
Introduction:
The storm drainage technical information report has been prepared to
address the City of Auburn's site development and storm drainage
requirements for the proposed HS Replacement: General Classroom
Building located inside Green River Community College at 12401 SE 320th
Street, Auburn, WA 98092. The project site has an area of approximately
2.8 acres and is currently occupied by six small buildings and associated
walkways. The small buildings will be demolished. A new classroom
building with associated walkways will be constructed at the site.
The subject site will be occupied by a new, three -story building. The site
will be re- graded to provide easy access to the new building and promote
positive drainage away from the building. The site will have more open
space than in its current conditions. Walkways, drainage systems, and
utilities on site will be replaced to serve the new building.
According to the City of Auburn's Construction Standards for storm water
management, the city requires storm water quality control to the proposed
redevelopment. We have proposed to collect all of the storm water runoff
from the landscaped, building and pavement areas in a series of catch
basins. This water will be conveyed by storm drainage pipe to two
Stormceptor systems for storm water quality treatments.
Storm Water Easement and Maintenance Agreement
Page 7 of 14
The Stormceptor systems are located southeast and northwest of the
project site respectively Here from the Stormceptor located at the
southeast corner, the storm water will be released into a 12" proposed
storm drainage line running to the east connecting into an existing 18"
culvert crossing under a parking lot. The culvert discharges water to the
campus drainage system, which drains to the Green River From the
Stormceptor located at the northwest corner, the storm water will be
released into a 8" proposed storm drainage line day - lighted to a ditch. The
ditch runs south and discharges water to the campus drainage system,
which drains to the Green River
Storm water quantity control is not required for this project because there
will not be an increase in the peak discharge from the re- development.
Plan Goal:
The specific purpose for the storm water facility is to minimize pollution that
is typically associated with modern development. In general, pollution from
motor vehicles and pollution generated from erosion. Attached to this
narrative is a maintenance manual, which offers guidelines to the owner for
storm water facility maintenance.
Prevention BMP'S:
The catch basins shall have stenciled on them "DUMP NO WASTE —
DRAINS TO STREAM." The owner shall be responsible for sweeping the
lot, installing storm drainage stenciling and provide spill control procedures.
In case of spill call DOE at 1-425- 649 -7000 The catch basins and
Stormceptor systems will be visually inspected for accumulation of debris
and silt and will be maintained as required by this pollution prevention plan
and attachments.

Ecology Storm Water Manual, August 2001)
No 5 — Catch Basins
Other — Stormceptor Systems
Storm Water Easement and Maintenance Agreement
Page 8 of 14
Treatment BMP'S:
Two Stormceptor systems have been installed to treat runoff for
conventional pollutants. The Stormceptor systems were designed to treat
64% of the 2 -year storm event (water quality storm) for water quality
treatment. The Stormceptor systems were designed to remove minimum
80% of the total suspended solids (TSS). Storm water detention for
quantity control is not required for the project because of minimal increase
in peak discharges.
Inspection /Maintenance:
Regular inspections of the drainage facilities should be carried out twice per
year, in the spring and fall. The responsible party should keep records of
these inspections available for review by the City. Additional inspections
may be required after severe storms.
Routine maintenance of the site will include mowing, care of landscaping
and the removal of trash and debris from the drainage system. The parking
lots and driveways should be kept clean and in repair Events such as
major storms or heavy winds will require immediate inspections for
damages.
To ensure proper water quality and treatment, the Stormceptor systems
must be properly maintained. Be careful to avoid introducing landscape
fertilizer to receiving waters or groundwater
Catch basins shall be cleaned when sump is 1/3' full of sediment or debris

Maintenance Standards for Drainage Facilities:
The facility- specific maintenance standards contained in this section are
intended to be conditions for determining if maintenance actions are
required as identified through inspection. They are not intended to be
measures of the facility's required condition at all times between
inspections. In other words, exceeding these conditions at any time
between inspections and /or maintenance does not automatically constitute
a violation of these standards. However, based upon inspection
observations, the inspection and maintenance schedules shall be adjusted
to minimize the length of time that a facility is in a condition that requires a
maintenance action.
